The Interagency Security Classification Appeals Panel (ISCAP), the highest declassification authority in the Executive Branch of the U.S. Federal Government, housed at the National Archives, has declassified 29 new documents relating to the government’s investigations into the 9/11 attacks, and they reveal new damning details about the Saudi Royal Family’s deep involvement in those Sept. 11, 2001 attacks.

From the time of his first campaign for President in 2008, Obama has promised the families of the 9/11 victims that he would declassify the 28 pages from the original Joint Congressional Inquiry, which detail the Saudi involvement in those heinous attacks. He not only broke that promise. He has consistently protected the Saudis from justice over their role in 9/11, and is now openly showing his hand by pledging to veto the Justice Against Sponsors of Terrorism Act (JASTA), now before the Congress, just prior to Obama’s now-ongoing visit to Saudi Arabia. The President has sold out the American people to his slavish loyalty to the Saudis and their British patrons. This is a crime that demands, at minimum, President Obama’s immediate impeachment from office.

The 29 documents, most recently declassified, contain work sheets, interview notes, and other documents from the 9/11 Commission, that make clear that the Federal investigators probing the Sept. 11, 2001 attacks had compiled massive amounts of evidence of direct involvement by agents of the Saudi Royal Family, the Saudi Ministry of Religious Affairs, and the Saudi Ministry of Defense and Aviation. They provide a backdrop to the suppressed 28-page chapter from the earlier Joint Inquiry, which merely summarized the volumes of evidence compiled—and covered up—about the direct Saudi government complicity in 9/11.

Perhaps the single most damning document, declassified last year, is a 47-page memorandum by Dana Leseman and Michael Jacobson, detailing all of the Saudi government officials who were implicated in the 9/11 attacks. Leseman was a Justice Department attorney and Jacobson was an FBI Special Agent. Both had served as key investigators for the Joint Inquiry, and had authored the 28-page chapter that Presidents George W. Bush and Barack Obama have suppressed. They went on to work for the 9/11 Commission, where their efforts to pursue the Saudi leads from their earlier work were stymied by Commission director Philip Zelikow. Leseman was ultimately fired by Zelikow for refusing to obey his orders to stop the probe of Saudi Royals’ ties to 9/11.

The 47-page document identified a total of 21 confirmed and suspected Saudi government employees who abetted the San Diego hijackers cell during the year-and-a-half that they were in the United States preceding the Sept. 11, 2001 attacks. The document detailed all of their roles in supporting the two West Coast hijackers, Nawaf al-Hazmi and Khalid al-Mihdhar. It also called for a thorough investigation of the FBI, which had an informant in San Diego who housed the two 9/11 hijackers in his home for months before the attacks.

One of the central figures linking the Saudi regime to the 9/11 plotters was Omar al-Bayoumi, a Saudi intelligence agent who was the main financier of al-Hazmi and al-Mihdhar during their entire time in the United States. In addition to his no-show job, with a sizeable expense account from a Saudi Ministry of Defense and aviation contractor, Dallah Aviation, al-Bayoumi earlier received $400,000 from the Saudi Ministry of Religious Affairs during the 1990s, ostensibly to build a mosque in the San Diego area. Investigators believed that those funds may have been used to build up terrorist cells in the area. These beliefs were buttressed by the fact that the San Diego mosque was run by Anwar Al-Awlaki, a spiritual leader of al-Qaeda, who was ultimately killed in a U.S. drone strike in Yemen—and who may have also been an FBI informant.

The evidence of deep Saudi involvement is almost matched in the 47-page document by evidence of FBI coverup of the 9/11 story. One segment of the recently declassified “Document 17” featured a series of questions about FBI stonewalling and coverup.

The document posed the following two questions: “1. Did the FBI intentionally withhold from the Joint Inquiry information about the informant’s relationship with the hijackers and subsequently attempt to obstruct the Joint Inquiry’s investigation of the matter?

“2. If the FBI did withhold information and obstruct the Joint Inquiry’s investigation, were the FBI’s actions indicative of a larger pattern of FBI non-compliance with Congressional oversight? What changes would therefore be needed to ensure more effective Congressional oversight of the FBI?”

A thorough review of all of the newly released documents is now underway. But sufficient evidence is already reviewed, proving the deep Saudi role in 9/11 and the ongoing coverup by President Obama and top officials of the FBI.

The evidence of President Obama’s witting role in this coverup already meets and passes the Constitutional standards of “high crimes and misdemeanors” requiring impeachment proceedings. There are credible reports circulating in Washington that President Obama is using his current visit to Saudi Arabia to solicit funds from the Saudi Royals for his post-presidential library and career—perhaps in return for guarantees that the 9/11 story will continued to be covered up at the top. Is there any justification for delaying one moment more the launching of those long-overdue impeachment proceedings?
